I'll use this function for performance improvements of XMLParser (bug 43085).

Maybe I'll move the function into AtomicString for inlineing.

Attached patch was modifying "equalIgnoringCase" - which was removed in below commit:

https://github.com/WebKit/WebKit/commit/507aa34586fdcf0b9a5ea433c2402f295a717da8

Further - "createStrippingNullCharactersSlowCase" - it had only one commit below:

https://github.com/WebKit/WebKit/commit/663efc5d78ea61ca1b418dbd67f3cd91676910a2

but even it was removed here:

https://github.com/WebKit/WebKit/commit/539e5655d6da61859c0f9448691eea1892cae8bc

So I don't think this patch can be applied to Github main / trunk / master branch since it has been changed drastically.

Can someone comment whether it is something needed out of this or this can be marked as "RESOLVED WONTFIX"? Thanks!

We have such functions now.

WTF_EXPORT_PRIVATE bool equal(const StringImpl*, const LChar*, unsigned);
WTF_EXPORT_PRIVATE bool equal(const StringImpl*, const UChar*, unsigned);
ALWAYS_INLINE bool equal(const StringImpl* a, ASCIILiteral b) { return equal(a, b.characters8(), b.length()); }
inline bool equal(const StringImpl* a, const char* b, unsigned length) { return equal(a, reinterpret_cast<const LChar*>(b), length); }
